New Orleans Saints defensive coordinator Gregg Williams could emerge as a possible candidate for the Tennessee Titans' head coaching job to replace Jeff Fisher because of Williams' ties to the organization. But it's unclear if he would be interested in the job.

Williams spent 1990 to 2000 as a Titans/Houston Oilers assistant, mostly under Fisher, who parted ways with the team Thursday night. And Williams still has ties to Titans owner Bud Adams and some of the current coaching staff.

But Williams recently pulled himself out of consideration for the Denver Broncos head coaching job that went to John Fox, insisting that it would take a special opportunity for him to leave New Orleans. And he has often stressed the importance of a stable quarterback situation. The Titans have announced they plan to release QB Vince Young in March.

Also, Williams always has considered Fisher as his closest friend in the business, so it's unknown if he wants to be the one who replaces him. No doubt, Williams would pick Fisher's brain before considering any such move.
